This article helps you fix if while installing skype messenger you get this error message:
you already have a download started, make sure SkypeSetup.exe is removed to continue(code 1618)
Solution:
1. Simply restart your computer twice. It should solve the problem itself.
2. If restart does not fix the issue, then try editing registry keys values:
- Goto: start -> run and type: regedit
- browse to: HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\InProgress
- clean / delete any registry entries that you find there.
- again navigate to: HKLM\System\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations
- and clean / delete all registry values your find there too.
This should solve the problem with skype installation that skypesetup.exe is removed etc.
Update: This method also solves the issue: (Thanks to user SzG)
You have update(s), which stucked in.
Control Panel->AdministrativeTools->Services->WindowsInstaller->
properties->set startup Type to [b]Disabled[/b].
**reboot**
after reboot there will be a message: The windows installer cant start, blah…blah… Click OK, and the stucked updates will finish.
Before reboot, Control Panel->AdministrativeTools->Services-> WindowsInstaller-> properties->set startup Type to [b]Manual[/b].
**reboot***
The updates will finish. Try install skype.
It worked for me under Vista.
